Zusammenfassung:The present invention relates to an asphalt mixture having improved waterproof properties by increasing binder content while maintaining interlocking, which comprises 89-90 wt% of a mixed aggregate and 8-9 wt% of an asphalt binder and has a porosity ratio of 2-3%, wherein the mixed aggregate has, based on a sieve and weight percentages, 100 wt% of a 20 mm sieve penetration rate, 96.5-100 wt% of a 13 mm sieve penetration rate, 50-55 wt% of a 10 mm sieve penetration rate, 16.5-30 wt% of a 5 mm sieve penetration rate, 12.75-23 wt% of a 2.5 mm sieve penetration rate, 10-18 wt% of a 0.6 mm sieve penetration rate, 8.25-15 wt% of a 0.3 mm sieve penetration rate, 8-15 wt% of a 0.15 mm sieve penetration rate, and 7-13 wt% of a 0.08 mm sieve penetration rate. 본 발명은 혼합골재 89 내지 90중량%, 아스팔트바인더 8 내지 9중량%를 포함하고, 공극률이 2 내지 3%로서, 상기 혼합골재는 체통과 중량백분율을 기준으로 20mm체 통과율은 100 중량%, 13mm체 통과율은 96.5 내지 100중량%, 10mm체 통과율은 50 내지 55중량%, 5mm체 통과율은 16.5 내지 30중량%, 2.5mm체 통과율은 12.75 내지 23중량%, 0.6mm 체 통과율은 10 내지 18중량%, 0.3mm체 통과율은 8.25 내지 15중량%, 0.15mm체 통과율은 8 내지 15중량%, 0.08mm체 통과율은 7 내지 13중량%인 것을 특징으로 하는 인터록킹이 유지되면서 바인더 함량을 증가시켜 방수성을 향상시킨 아스팔트 혼합물에 관한 것이다.
